Cleaning the Exhaust Gas Recirculation Valve

Model: Ford Fiesta Fiesta 4, Be91, MK 4, MK IV - Years 1996-2002
Part: Air filter

First, let's explain the problem: the exhaust gas recirculation valve is connected to the intake manifold. Under certain circumstances, it opens to inject exhaust gas into the engine's intake manifold. Sometimes the valves can get stuck due to dirt, wear, or other factors and need to be replaced. An alternative to replacement is cleaning. This video shows a method for cleaning them using a special spray. In reality, both the method (with the engine running) and the product used may raise some doubts about the effectiveness of the operation, as well as its safety.
